FIRST LEGO League (FLL) is the most popular LEGO Mindstorms Robotics Competition. Each year the season starts in Augusts and completes by May. We've created a lot of resources for FIRST LEGO League to help teams prepared, learn and have fun. Here are most of the tutorials, building instructions and courses for FLL
Here we collect resources that are common for most LEGO Mindstorms robotics competitions. The resources here could be used for FLL, WRO, general line following, sumo and many more.
Learn how to build LEGO robots and win the FIRST LEGO League competition.
Using LEGO Mindstorms EV3 and NXT robotics kits we give curriculum ideas, share professional experience and teach students to think and develop as engineers. The goal of this category is to group specific examples from specific missions.
Contains resources for LEGO Mindstorms competitions. There are many LEGO competitions using EV3, NXT and RCX robots. These competitions have some similarities, but could be quite different in general. Most popular are of course FIRST LEGO League and World Robotics Olympiad.

Gapped and Crossed Line Following with LEGO Mindstorms. Part 1. Challenge. Use of State Machines
We start a course for following a line with crosses and gaps. This is a challenge that one of the users at FLLCasts.com was trying to accomplish and asked us for advice. We present the whole challenge to you step-by-step. But first, let's also see the whole run of the line following algorithm. With this course, we also do an introduction of using State Machine as a programming pattern.

Gapped & Crossed Line Following. Part 2. Strategy
Looking at the field we must first think of a strategy of solving this line following problem. There are rules that the robot must follow and these rules should be programmed in the robot.

The robot is not at the right position at the end of the straight movement?
This is where the confusion really comes. We are keeping the robot orientation straight while the robot moves, but at the end the, robot is not at the fiinal location that we would like it to be. The robot is still about 2-3 centimeters away after moving for about a meter.

How to calibrate more than one LEGO Mindstorms EV3 Light/Color sensors at a time
Would you like to resolve all the problems with the light/color sensors that you have? And to make all of them work in a predictable, stable way even when using more than one MINDSTORMS colour sensors.
When using Color sensors it is important to calibrate them depending on the light conditions in your venue. In this way, the calibrated sensor will show values between 0 and 100 independent of the light conditions. But using the default EV3 colour calibration available in the colour sensor block could lead to unpredicted problems that are difficult to track and resolved especially when used with multiple Color sensors. So in this series of tutorial we implement the calibration ourselves discussing the principles of colour sensor calibration.
